The 870919BRI-01LF is a type of low-cost, high-performance clock generator chip from Intersil. It is used to generate precise clock signals for a variety of digital signals and multiprocessor applications. It is a single-stage, 6th order, gated voltage-controlled oscillator (VCO) with a wide tuning range, providing excellent jitter performance.

The device combines the features of a VCO, a PLL and a frequency synthesizer on a single chip, allowing for increased levels of integration and system performance. Its low-voltage operation and high-efficiency design make it ideal for low-power, low-cost applications. This makes it suitable for use in automotive, medical, consumer and industrial applications.

The 870919BRI-01LF has two primary components: a VCO, and a PLL. The VCO is a frequency-determining element that generates an output frequency based on the input control voltage. This voltage is supplied by the PLL, which locks the output of the VCO to a desired frequency. The PLL also contains a reference oscillator and a loop filter in order to stabilize the output of the VCO. The overall frequency is determined by the input control voltage, the reference oscillator frequency, and the loop filter.

The 870919BRI-01LF has a wide frequency range, ranging from 0.3MHz to 750MHz. It features a low supply voltage operating range of 1.8V to 3.6V and a low power consumption of only 0.75mW. It also integrates a dual 10-bit programmable divider and 99 programmable dividers for higher levels of integration. Furthermore, it offers programmable output swing, selectable slew rate, high-sensitivity VCO control, and different spread spectrum modes.

In addition, the 870919BRI-01LF has excellent jitter performance, with a single-sideband phase jitter of 0.4ps RMS. It also offers fast lock, settling and hold times, with settling times as low as 1.2µs and lock times as low as 3µs.

The 870919BRI-01LF is ideal for applications that require a low-cost, low-power, and high-performance clock generator. It is suitable for use in automotive, medical, consumer, industrial and multimedia systems such as digital TV, digital audio, digital cameras and digital video players. Its low- voltage operation and high-efficiency design make it ideal for low- power, low-cost applications.
